Diffusion metrics estimates (mean ± standard error of the mean (SEM)) in each brain region of interest for the 8 months old mice. One-way ANOVA with significant p-values in bold; a (*) indicates that the group difference remained significant after applying Bonferroni correction. Mean diffusivity (MD); axial diffusivity (D‖); radial diffusivity (D⊥); mean kurtosis (MK); axial kurtosis (K‖); radial kurtosis (K⊥); Ts65Dn (TS; n=4) and normossomic control (NS; n=8) groups; frontal cortex (FC), cortex (CT), striatum (ST) and hippocampus (total – HT; dorsal – HD; ventral – HV)
